It has some reasonably flat sides in an almost = irregular cube shape. It was found 18 inches underground and in the = middle of nowhere. I have seen a few stony meteorites which have similar = shapes, but my question is 'can irons have a fairly cubed-type shape = too?' Also, does anyone know how the density of mesosiderites compares with = irons and can mesos also go quite rusty when old and weathered? Any = thoughts would be appreciated.
